(ZZZ whom it may concern:

Belt known that T, DANIEL J. Minimise, a citizen or the imited btates,residing at Kirkwood, St. Louis county, Missouri, have invented acertain new and useful Improvement in Devices for Connecting Plates ofGlass Together, of which the following is a full, clear, and exactdescription, such as" will enable others skilled in the art to which itappertains to make and use the same, ref erence being had to theaccompanying drawings, forming part of this specification, in whichFigure l is a perspective view illustrating my improved device inoperative position for connecting together two plates of glass arrangedat an angle to each other; Fig. 2 1s a cross sectional view taken 011the line 2-2 of Fig. 1; Fig. 3 1s, a detail perspective view of one ofthe devices which embrace the outside clamping member; Fig. at is across. sectional view illustrating a modified formof my invention; Fig.dis a cross sectional view illustrating another form of my invention;Fig. 6 is a perspective view illustrating still another form of myinvention; and- F T is a cross sectional view taken on the line 7-? ofFig. 6.

This invention relates to devices for connecting together two plates ofglass, such, for example, as the devices used in the construction ofshow-cases and corner windows.

The main object of my invention is to provide a device for the purposedescribed that is of simple construction and which presents a neat andornamental appearance.

Another objectof my invention is to pro vide a device for the purposedescribd of iuu'n'oved construction which is provided with anon-metallic abutment or a plurality of non-metallic abutments thatengage the edge portions of the plates of glass and thus prevent themfrom contacting with the part that con ects the inside and outsideclamping members of the device together.

Other desirable features of my invention will be hereinafter pointedout.

Referring to Fig. 1 of the drawings which illustrates one form of myinvention, 1 designates two plates of glass arranged at an angle to eachother, and 2 designates an outside clamping member that extendsapproximately the entire length of said plates so as to protect same,said member preferably consisting of a piece of comparatively thin orlight-weight angle iron that engages the outside faces of the plates ofglass 1. This angle or outside clamping member 2 preferably has shortlegs or flanges so that it will cover only a small portion of theplates,

thus forming a small and neat corner-piece that prevents dust and dirtfrom entering the joint between the plates of glass.

Inside clamping members 3 which may be of any preferred construction,are arranged on the inside of the plates 1, as shown in Fig. 2, andmeans are provided for drawing the outside clamping member 2 and theinside clamping members 3 together so that they will securely clamp theplates of glass arranged between them. In the form of my invention shownin Figs. 1 and 2 the out side clamping member 2 and the inside clampingmembers 3 are held in intimate engagement with the plates 1 by means ofscrews i passing throu h the inside clamping members 3 and engagingdevices 5 that embrace the outside clamping member 2, one of saiddevices 5 being provided for each inside clamping member 3. The devices5 conform in shape to. the outside clamping .side of the plates 1. Inthis way I am on abled to use a very small outside cornerpiece andinside clamping members that are of sufficient size to obtain a firmbearing on the plates of glass, the portions of the devices 5 whichproject beyond the edges of the outside clamping member being arrangedin alinemeut with the inside clamping members and thus hiding same. Eachof the devices 5 is provided with a central lug or thickened portion 6having a screw-threaded opening 7 that receives the screw 4., and thecorner of the outside clamping meml er 2 is notched or cut away, asshown in Fig. 2, and also in dotted lines in Fig. 1, to pr vide aclearance for this lug 7 and thus permit the device 5 to snugly embracethe outside clamping member and force it into intimate engagement withthe plates of glass.

Non-metallic abutments, preferably blocks of wood 8, of greater width orthickness than the screws, are arranged between the edge portions of theplates of glass 1 so as to prevent said plates from contacting with thescrews i or other fastening devices that may be used for securing theoutside clamping member and the inside clamping members Patented Aug.24:, 1909.

together. In the form of my invention shown in Figs. 1, 2 and 8, thesenon-metallic abutments 8 are carried by the devlces 5 which embrace theoutside clamping member, each abutment being provided with a shank thatprojects into an opening 1n the thickened portion of the device 5 1nal1nement with the screw 4, the notch or cut-out portion in the cornerof the outside clamping member being large enough to permit theabutments 8 to project therethrough and as said abutments are of greaterwidth or thickness than the screws 4 they will prevent the edges of theplates of glass from contacting with said screws.

Instead of connecting the abutments 8 to the devices 5 I can form saidabutments as shown in Fig. 4. In this form of my invention the abutmentsconsist of wooden blocks 8 that rest upon or are supported by the screws4, said blocks conforming in cross section to the space between theplates of glass and having portions which project inwardly between theinside edges of said plates to hold them out of contact with the screws4. If desired, the abutment 8*, shown in Fig. 4, can consist of onecontinuous strip provided with openings for receiving the screws 4. ThisFig. 4 also illustrates a slightly different means for connecting thedevices 5 and inside clamping members together, each of said devices 5being provided with an integral screw-threaded shank 4 that passesthrough an'opening in the inside clamping member and having a nut 4mounted on the inner end thereof. In Fig. 5 I have also shown anotherway in which the abutments can be held in position. In the form shown insaid figure the outside clamping member 2 is provided on its inner facewith lugs or thickened portions 2 that may be formed by solder or in anymanner desired, and the abutments 8 are secured to these lugs 2 andproject inwardly between the edges of the plates of glass so as to holdthem out of contact with the screws 4.

Instead of using devices 5 to force the outside clamping member againstthe plates of glass, said outside clamping member may be provided on itsinside with thickened portions or lugs 2 having screw-threaded openingsthat receive the screws 4 which pass through the inside clamping members3, as shown in Fig. 6, the abutments 8 also being connected to lugs orthickened portions 2 on the inside corner of the clamping member 2, asshown in Fig. 7. These lugs or thickened portions 2 and 2 on the insidecorner of the clamping member 2 can be formed from any suitablematerial, and if desired, the outside clamping member can be providedthroughout its entire length with a thickened portion at the junction ofits two legs or flanges. The outside clamping member shown in Fig. 6, isprovided with integral laterally projecting wings 5 that located inalinement with the inside clamping members 3 for the purpose of hidingsaid members, said wings performing the same function as the portions ofthe devices- 5 that project beyond the edges of the out-' side clampingmember 2, as shown in Fig. 1.-

lVhile I have herein shown screws for drawing the inside and outsideclamping members into intimate engagement with the plates, it will, ofcourse, be understood that the inside clamping members could beconnected to the outside clamping member or to the devices which embracesame in numerous other ways without departing from the spirit of myinvention.

Having thus described myinvention, what I claim as new and desire tosecure by Letters Patent is:

1. A device for the purpose described, comprising a continuous outsideclamping member that is adapted to be placed in enga ement with twoplates of glass arranged ad acent each other, a plurality of devicesthat embrace said member and hold it in position, a plurality of insideclamping members, means for drawing said devices and inside clampingmembers toward each other, and a non-metallic block carried by each ofsaid devices and projecting inwardly biatween the meeting edges of theplates of g ass.

2. A device for the purpose described, comprising an outside clampingmember, an inside clamping member, a metallic device passing through theinside clamping mem- 1 ber and connected to the inner face of theoutside clamping member for drawing said members toward each other, anda non-metallic block connected to the outside clamping member andprojecting inwardly between the meeting edges of the plates of glassthat said clampin members retain in position so as to hold said platesaway from said metallic connecting device.

3.
